When it comes to raising up a bunch of crustaceans, you may be surprised to find out that just like reptiles, they need an outside source of warmth to get their metabolic juices flowing. However, since the lamp that your cold-blooded friends are using may be too much for these species, you may want to try the Zoo Med Laboratories Hermit Crab Heater from Pet Store instead. Unlike other brands, this has received an approval from UL, which is a company that checks for the quality and performance of machines, especially those that will be utilized for the benefit of living creatures.
This tool is quite small, and it is equipped with a long cord, which will allow you to set this up however you like. To maximize the space inside the home of your crabs, you may want to consider hanging the heater via cables, or simply concealing it in a far corner to keep your pets safe, and prevent any burning. This product can only produce up to 160 watts of light and temperature, which is just right for these species. This device is encased in a durable sheath that is designed to endure high heat.
With the Zoo Med Laboratories Hermit Crab Heater, your crustaceans will feel more at home under the glow of a machine, which gives off the perfect temperature that they rely on.
A 4 watt adhesive heater that is UL approved for plastic "keeper" type cages. Raises the ambient temperature in small terrariums about five degrees.
